stand af iiæsten en halv Hovedlængde fra Anus. dog for- 

 lioldsvis langt fortil, idet dens Afstand fra Snudespidsen 

 blot udgjør en Trediedel af Totallængden, saaledes at det , 

 egentlige Haleparti kommer til at udgjore 2 Trediedele af 

 denne. 



Caudalen er særdeles smal og langstrakt, samt ubety- 

 deligt tilspidset. Den bestaar af 10 særdeles line og tæt- 

 stillede Straaler. livoraf det vderste Par ere kortere, end . 

 de ovrige, der samtlige omtrent have samme Læugde; de. 

 ere udelte, men fint articulerede. Caudalen, der. som oven- 

 for uævnt, ved Roden er beda^kket af den sidste Dorsal- 

 og Analstraale, har en Længde af omtr. '/m af Totall. 



Pectoralerne udspringe uoget bageufor Anus, lige 

 bag Gjællespalten, saaledes. at deres Rod berøres af Gjælle- 

 hinden. De tælle 11. paa den anden Side 12 Straaler, der 

 ere delte omtrent fra Midten af. Pectoraleus (irundlinie 

 udgjør lidt over Halvdelen af Interorbitalrummets Bredde. 

 De «verste Straaler ere de bengste. de følgende eiterhaan- 

 den kortere ; deres storste Længde indeholdes i Totalhengden 

 næsteu 7 Gange. Hele Finnen er yderst blød og bojelig. samt 

 halvt gjeunemsigtig, og iudhyllet i den samme lose Hud, 

 som den øvrige Del af Legemet. 



"\"'entralerne ere tilstede som 2 lange Filamenter, hver 

 indhyllet i en tyk 'Hud, og fa^stede til Tungebenet. umid- 

 delbart ved Gjællespaltens nedre Ende. I sin første Halv- 

 del ere de udelte, men dele sig paa Midten i 2 Traade, 

 hvoraf den ene er hengere, end den anden. Ventralens 

 hele Læugde udgjør hos det eneste undersøgte Lidivid om- 

 trent ^/a af Legemets Længde, men varierer sandsynligvis 

 hos Lidividerne. 



Slimporer. Sidelinie eller Skja4 tindes ikke. Langs ' 

 Uuderkjæven strækker sig en Række af 4 store, aabne Po- 

 rer, hvoraf den første staar nærved Symphysen. den sidste 

 paa Kjieveus bagre Rand. Paa hver Side af Overkjæven, 

 umiddelbart ved Randen, staa 3 lignende Porer, samt eu 

 enkelt paa hver Side hen under Øjet. 



Farven var overalt mørkt kjodrød med enkelte lysere 

 Skygninger; den var yderst fint og jevnt fordelt, saaledes 

 at tydelige Pigmentpunkter vare ikke synlige. Gjællehinden 

 var intens carmosinrød ; Iris var ikke metalliskfarvet, men 

 dybt blaasort. Denne smukke røde Farve er efterhaanden 

 hos det paa Spiritus opbevarede Exemplar saagodtsom 

 ganske forsvundet. saaledes at dette nu er bleven jevnt 

 hvidagtigt overalt. 



Appendices pylorieae, hvis Antal var 10. vare tykke og 

 cylindriske; deres Længde varierede mellem 15'""' og 18""". 

 Bughinden var sort. 



Individet var en Han; Testes, der dog neppe for 

 Tiden vare i sin fulde Udvikliug, havde en Længde af 45 """ 

 (den venstre), og 55'"'" (den hojre). 



Føde. Yentrikelen, der var san-deles musculøs. inde- 

 holdt endnu gjenkj endelige Levninger af Crustaceer, skjønt 

 Individet var ophentet fra den enorme Dybde af næsten 

 1 300 Favne, hvortil- var medgaaet flere Timer, og derpaa 

 i en Tid holdt levende ombord. Disse vare 2 Individer 



commences nearly half the length of the head posterior to 

 the vent, but comparatively far in front, being distant not 

 more than one-third of the total length from the tip of 

 the snout; and hence the caudal portion of the body equals 

 two-thirds of that length. 



The caudal is narrow, elongated, and very slightly 

 pointed. It. consists of 10 exceedingly close and slender 

 rays; the outermost pair shorter than the rest, which are 

 nearly uniform in length; they are simple, but minutely 

 articulated. The caudal, covered at the base (as stated 

 above) by the terminal ray in the dorsal and anal, is equal 

 in length to about one-tenth of the total length. 



The pectorals commence a short distance posterior 

 to the vent, immediately behind the liranchial opening, their 

 base in contact with the branchial meml)rané. They are 

 furnished on one side with 11. on the other with 12 rays, 

 divided from about the middle. The base of the pectorals 

 measures rather more than half the width of the interorbital 

 space. The upjiermost rays are the longest, the rest be- 

 coming gradually shorter ;' their length . is to total length 

 nearly as 1 to 7. The whole tin exceedingly soft and flexible. 

 also semi-transparent, and, like the rest of the body, envel- 

 oped in a lax integument. 



The ventrals occur as two long filaments, each invested 

 with a thick membrane, and attached to the hyoid bone, 

 close to the lower extremity of the gill-openings. In their 

 first half simple, but divided about the middle of the fin 

 into two cirri, one longer than the other. The length of 

 the ventrals in this unicum equals about one-third of the 

 length of tlie body, but will probably be found to vary in 

 difi'erent examples. • 



Mucous Fores. — No scales or lateral line. Along 

 the under surface, however, extends a row of 4 large, open 

 pores, the first in close proximity to the symphysis, the last 

 on the posterior margin of the jaw. On either side of the 

 upper jaw, contiguous with th.e margin, are three similar 

 pores, and a solitary pore occurs under each eye. 



CoJonr. — The whole body of a bright red colour, 

 here and there with lighter-tinted cloudings; and this 

 ground-colour being remarkably uniform, no distinct pig- 

 mentary specklets were observable. Branchial membrane the 

 brightest of crimsons; irides a deep bluish-black, without 

 metallic lustre. The beautiful red colour has gradually 

 faded, from the action of alcohol (the sjjecimen is preserved 

 in spirits), the fish being now uniformly whitish. 



Fyloric appendages 10, thick and cyliudric. varying 

 in length from 15""" to 18""": ventral membrane black. 



This individual was a male ; length of testes, which, 

 however, had hardly then attained their full development, 

 45'"'" (the left) and 55'"'" (the right). 



Food. — The ventricle — exceedingly muscular — 

 contained still determinable fragments of crustaceans (and yet 

 the specimen was brought up from the great dejjfh of 1300 

 fathoms, which took several hours; and it was kept, too, 

 some time alive), viz. 2 examples of Bijtliocaris leucopis,
